Which of the following is one method to eliminate or reduce the presence of Greater Wax Moths?

The method of storing frames in unheated areas during winter is effective for reducing the presence of Greater Wax Moths. These pests thrive in warmer temperatures where they can reproduce and infest beekeeping equipment. Cold temperatures hinder their life cycle and significantly reduce their activity and survival rates. By storing frames in unheated conditions, beekeepers can effectively disrupt the moths' breeding and development, making this an important management strategy.

On the other hand, storing frames in heated areas might create an ideal environment for the moths to thrive, while maintaining a weak colony can actually attract these pests, as fewer worker bees may not protect the hive as effectively. Keeping frames on the ground exposes them to environmental conditions that may not be ideal for pest management, plus it can increase the risk of rodent damage and other issues. Thus, storing frames in unheated areas is the most beneficial practice in this context.
